LT1 Dyno Results - with graph
Just got my car dyno tuned by Bryan Herter. Here is what we ended up with:
387 RWHP / 366 RWTQ in FULL Emissions trim, including Cats, EGR and AIR. This final pull was done with a warm motor.
HP peaked at 6150rpm and the TQ peaked between 4500 and 5000. The TQ curve was VERY flat making over 350 lb-ft from 2000rpm through 5800rpm. Peak HP didn't start falling off until 6400rpm. the car is extremely responsive and makes power from 1500 through redline!!!
-LE2 Heads
-LE1 Emissions Cam. Duration is in the low-mid 220s with a wide LSA.
-355 LT1 shortblock by D&F Performance in Williamstown, NJ
-1.6 Rockers
-58mm TB
-Stock intake with TB holes opend up to match the 58mm TB
-30 lb Ford injectors
-Jet Hot LTs with emissions fittings
-Mufflex 3.5" exhaust and y-pipe with 3" cats (not hollowed out)
-6M with 4:10s
I just like to give a special thanks to Lloyd Elliot for flat-out nailing the combo, to Dave at D&F Performance for doing a superb job with the SB and engine assembly and to Bryan Herter for his tuning abilities. We picked up almost 20hp on the dyno. Well Done!!

Nice numbers! Where did he dyno tune the car at? Your just across the street from me too
Bryan is going to tune my car wen I get it back together but its taking a bit longer than I had expected. Bryan is top notch!
Where is D&F? Never heard of them before. What's in the short block?

I wanted setup that was driveable and responsive. Yes, it is a blast to drive! 
I had it dyno'd at JD's in Huntington Valley. Bryan rents the shop dyno for tuning.
D&F is in Williamstown, NJ. They've been around for at least 20 years. They were amoung the 3 highly recommended SB chevy builders in the Philly area. No complaints! The short block is balanced, has forged pistons, it's squared, decked, etc. It has the stock crank and rods.
I hope to get to Atco within a few weeks.
I'll try to get the dyno sheet up shortly.

never heard of them before. I was curious because you said "forged 355". I assumed you meant crank and rods were forged also.
Yeah I've been to JD's before. Bryan will probably tune my car there also.
